Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed February 23, 1912. Serial No. 679,751.

To all whom/it may concern Be" it known that FREDRIG D. OGDEN, de-' ceased, formerly a citizen of the United States, and a resident of Bayonne, count of Hudson, and State of New Jersey, di prior to his decoase, invent certain new and useful Improvements in Doors and Means for Operating the Same, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof;

This invention relates to an improvement in'doors'and their operating mechanism,

and especially to such doors as are used for closing large openin s or doorways 1n pier sheds, factories, ware iouses, and tie like.

"The object of the invention is to royidc asimplo door and its operating mec amsm,

A applicable more particularly to what are view of the door and its mountin known as single-section doors, although obviously not limited to doors of this )articular type, which is inexpensive, an easily manipulated and which has advantages over suclrdeviccs as have been in use heretofore.

I will describe my invention in the following specification and point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is an inside front elevation of a door embodying the invention. Fig.2 is a transverse vertical section of the same. Fig. 3 is ai lar;

1g. is a fragmentary side elevation siowing a portion of the hoisting mechanism. Fig. 5 IS a sectional lan view of portions of the door and the door frame above the rollers 27-28 and Fig. (l is a similar section of like parts below the rollers.

As illustrated in the drawing, the door 10 is composed ofa single section of any ap-' proved construction, and arranged to close the space between the side we ls 12 of a doorway. The outer, face of the door adjacent its lower edge is provided with an angle'iron 14 having its lower flange rojecting from the face of the door. ihis liango rests upon the floor when the door is closed, and acts as a water-shed when the door israised to its dotted line position shown in Fig. 2.

A pair of Z-bars 16 are mounted on the side walls on each side of the door opening.

They extend fromtho floor up over the lower part of the opening and their inner flanges project slightly inside of the door opening and act as stops to limit the inward movement of the lower end of the door. A

' pair of locking bolts 18 may also be provided to secure the door in closed position. The lower part of the door is preferably formed without panels on the outside so as to provide a smooth surface which will readily shed water when the door is open.

The door is raised by two hoisting chains 20 and 21, connected at one end to swiveled arms 2223 respectively, at least one of which is rovided with a threaded eye-bolt or other covice for adjusting the length of the chain. These arms are pivotally mounted on studs 24 )rojecting from liloeks 25--26 respectively, which are mounted on the inner face of the door, intermediate the top and bottom thereof and ad'acent its edges. Rollers 27-28 are pivotally mounted on the studs 24 and as the door is raised roll on the inner face of the wall of the door opening on which tracks 19 are provided for them.

The pivots 24 also act as rolling pivotal centers or the door during its raising or lowering movement. The eiain 20 passes from the arm 22 over an idler sheave 30, which is pivotally mounted in a bracket 32, supported near the to) of the doorway; over one side of a doub e-grooved pocket wheel 84, carried by a shaft 35, mounted in a housing 86; and thence down to the counterwei ht 88 to which it is attached. The chain 21 passes over the other half of the double-grooved pocket wheel 34, and is also attachec to the counter-weight 88. 40 is a hand chain which passes over a chain sprocket 42 on a shaft 48, on which is a pinion at, which meshes with a gear 4.6 on the shaft 85 and thereby drives the double grooved pocket wheel 84. A pair of chains 5051 may be attached at one end to tho uper edge of the door, and at their other on s to the ceiling 52. If desired these chains may be attac ie door openin The chains 50-51 support the upper e ge of the door after it is raised and prevent its inner edge being pulled downward if any undue weight is placed upon it.

A pair of links -50 are pivotally mounted at their upper ends in bearings d to the wall above the yacentthe upper corners of thefdoorway. The lower cat s of those links are pivotal y mounted in brackets 59-00, respectively, se-

cared to opposite edges of the' inner face of the door. By pulling the chain 40 the double pocket sheave 34 ma be'rot-ated to raise or lower the door. Iy reference to Figs. 2 and 4, it will be seen that the upward pull on the door exertedby the chains 20-21, on the pivots 24 causes the door to be raised and at the same time t-he links 55-- 56 force the upper part of the door inward as the pivotal sup orts for the lower ends of the link in brac cots 59-60 are inside of lines drawn between pivots 57 or 58 and the pivots 24. As the door continues to move a ward therollers 27-28 roll up on the trnc ks 19 on the inner face of the wall 12 and the upper end of the door continues to be forced inward by the links 55-56 and finally assume some such .osition as that in which it is shown in dotted lines in Fig. 2.

The upper part of the door, or that part which is above the pivots 24 is made somewhat wider than the doorway, while the part below the pivots is narrower so that it may swing freely through the doorway This narrower part of the door abuts against the Z-bars when the door is closed.

From the foregoin" description it may be seen that the door w ien closed may form a wind andwater-proof closure, whie i may be readily raised into a position to leave the entire doorway clear. In its raised position part of the door rojcets outwardly from the structure thus Olllllll a canopy over the doorway. It may he s ightly inclined when inits raised position so that it will allow water to run otl' freely, and the angle iron is provided so that the water will drip from its corners only. It is usual to place the pivots 2t slightly below the center of the door, and when so placed about one belief the door will be inside and one half outside of the building when "the door is raised. This however is not essential as the ivots may be placed considerably above or )elow the center as long as they are in axial alinenient. Thus the proportion of the door which proieets-outside of the' building when the door is raised, ma be varied as desired. The angle of inc ination of the door in raised position may also be varied to suit requirements by proportioning the length and the positions of tlie'snppor s of the links aa-ae. The advantages of this construction wlienused for the doors ot' shipping rooms, freight houses, or other similar openings, are obvious. a v

I have described and claimed a structure with the upper part of tliedoor wider and the lower part narrower. than thedoorway, but it is o invention to invert this arrangement'andto 57 -58, respectively, secured to the wall 'ad-" vioiisly within the scope of this so chan e the mechanism that the upper part of the d oor may be swung outward to form a canopy.

What I claim-is:
